Not a huge fan of this headline. While it's true that we're locked in for a certain amount of warming, phrasing it as "it's too late" kind of implies "why bother", which is not a healthy attitude towards climate change.
Neither is we/they/AI/God will figure it out. I don't read the headline that way though, it's more a factual "there will be overheating, so get ready", which is totally appropriate.
The IPCC has always been thought of as being conservative in its estimates of climate change, so to hear Jim Skea, the Chair of the IPCC, say it’s too late is sobering
It seems to me that the newer the research is the sooner the estimates seem to be getting, so my money is on a collapse before 2050 and I wouldn't be surprised at all if it happens within a decade.
It's going to overheat first, just long enough for the folks there to spend billions of £ installing air conditioners, and then it's going to be plunged into a localized ice age.
